l Charcot Foot Pathogenesis: Requires peripheral neuropathy and repetitive microtrauma (often minor or completely forgotten by the patient).
l Charcot Foot Neuropathy: Involves both sensory-motor neuropathy (insensate walking) and autonomic neuropathy (increased blood flow).
l Charcot Foot Early Phase Presentation: Mimics cellulitis with localized erythema, warmth, swelling, and bounding foot pulses.
l Charcot Foot Deformity: Continued weight-bearing on an insensate, hyperemic foot leads to progressive joint destruction and the classic "rocker-bottom" foot.
l Charcot Foot Bounding Pulses: Autonomic neuropathy leads to arteriovenous shunting, creating bounding distal pulses despite active local destruction.
